- Stylish design - the first thing that caught my attention - the headphones are beautiful. The speakers rotate 90 degrees, which means that the headphones can be hung on a special mount in a backpack, for example, in the Xiaomi Geek Backpack. The arcs are adjusted individually to the size of the head - at the same time, they do not crack, click or play during adjustment. Could be considered full size, I guess. Because safely close the ears completely. The ear pads and headband are very soft and comfortable. And the seams are even. They sit tightly on the head, in this parameter I would compare with the studio ones. Soundproofing is comparable - heh - with building headphones: external sounds are much quieter, and if you yourself talk to someone with headphones on in standby mode, they tell you: "Don't yell." And you don't seem to be screaming. :D While listening, I personally did not hear anything interfering from the outside - unless, of course, it is a jackhammer nearby. :D Sound via Bluetooth can be described as quite decent. Bass is present. If you want a convex (ha ha) sound - Flat equalizer for Android will do you quite well - although without auxiliary means the sound is above average in quality. There is a detachable cable jack jack 3.5. About the sound on it - in shortcomings. The microphone is excellent. Talking on the phone through the headphones did not upset the audibility and transmission (and you, in fact, saw the microphone speaker here - take a look and understand!) I tested for 30 minutes at a volume from high to the highest - they were not discharged by 1% of the original charge level! In general, an impressive listening time - 40 hours and 200 hours of waiting - is just a lot.
- With a detachable jack jack 3.5 cable, the sound is quiet: you set it to almost full volume, at which the Bluetooth speakers tremble from the power of sound waves, but it turns out, as it were, a little above average. But, if the headphones are discharged (you never know, suddenly you listened for 40 hours without a break and it seemed to you not enough: D), you can listen further via the cable when turned off. More - I donโt even know what to complain about: in my opinion, an excellent choice - itโs surprising that the cost is so low. Yes, there are simply no extra charges for the megalomania of an eminent company, that's all.
